See this thread John - if it's not any of those, then identify the bush on the diagrams I posted over there and advise...

many thanks Marc

guessing 21 or 26

parts turned up just now as SS8039?

[GiveMeABreak]

21 is a bolt and 26 are square washer thingies John? SS8039 isn't a PSA part either, so a bit out in the ablutions John!

[jgra1]

lol thanks Marc
I couldn't see to well on the pic.

I bought these already,

https://www.ebay.co.uk/itm/401189936582 ... i&mail=sys

will get around to trying them soon. \just wondered more about getting the arm off the car really. looks like the bolts that go through the bushes wont come out enough without dropping the strut tops..

may have another look later or over the weekend

Ok, good luck - I left it to my local to do the lower bushes - he had no issues.

thanks Marc
just had another look, looks tough!

have you got a official how-to on removing the strut mount? dont worry if its buried and a load of hassle. The bushes look to be part of the strut mount - not the upper arm!

is the diagram linked before able to be a bit bigger? I cant seem to zoom on it, click it etc?

I only have the paperwork for pug unfortunately


the bushes I bought do look the right ones, which is good

[GiveMeABreak]

On any of the pictures / diagrams within my specific posts, they will zoom if you click on them John. So just to be clear, which part are you replacing?

[jgra1]

! that's better the other pic wont do that

part 11

Right, it will take me a while as the previous 'how to' guides I've done are typically all for different engines and yes, the blighters are all different!

And yes, you are going to have to remove the suspension strut and all that entails - which seems to be the more involved operation - the top mounting bushes are relatively easy by comparison! I will start on it now and shortly lock the thread as there are a lot of codes and formatting I need to do to get it all in here. So I will put it into 2 procedures - the Strut and secondly the Bushes for the Front Suspension Upper Support.

Replacing Bushes: Front Suspension Upper Support

Procedure Specifically for Citroen C5 X7 DW10CTED4 with Hydraulic Suspension Only

The bushes are shown at (11) on the diagram (click to zoom)

This operation necessitates the removal of the front hydraulic strut, so is in 2 parts.

Part 1 Hydraulic Suspension Strut Removal

Tools

[1] Hub Immobilising Tool 6310-T.	[2] Ball-Joint Extractor 1892-T.	[3] Spanner for removing "Slimline" spheres 8611-T.

Note: In this procedure you will find reference to replacing the seal shown at (23). There is no specific 'O' ring shown on the suspension strut parts diagram, however there are 3 'O' rings shown in the general suspension parts section, so I can't advise as to which one of the three this seal is:

(2) Part 5280Y2 (DIAM 10 MM) (3) Part 5280Q0 (DIAM 3.1 TOR 1.9) (4) Part 5280V9 (DIAM 4.75 MM)

Here is a link to my post detailing the Depressurisation, Draining, Filling and Bleeding of the Hydraulic Circuit with pictures. The hydraulic circuit needs to be depressurised before removing the Strut, so make sure you have a few litres of LDS fluid handy before commencing the operation.

Link to Hydraulic Draining, Filling / Bleeding Procedure

Removing

Disconnect the battery (Battery Disconnect / Reconnect Procedure)

• Lift and support the vehicle with the wheels free. (Remove LDS Cap first)
• Remove the front wheels.

Fit the tool [1]. The pin (1) The cover (2) The drive shaft nut (/) ESSENTIAL: Never brake to slacken the drive shaft nut.	Remove: The nut (3) The nut (4) The nut (5) and its pin
Remove: The anti-roll bar link rod (6) The nut (7) Uncouple the steering ball joint: Using tool [2].	Remove: The (8) bolt The (9) bolt The nut (10) The (11) bolt The (12) bolt The ABS sensor (13) Move aside the brake hose supports (14). Hold the driveshaft at the gearbox end (left side). CAUTION: Hold the end of the driveshaft to prevent an excessive angular travel (Risk of uncoupling). Detach the drive shaft from the hub.
Disconnect: The wires of the brake pad wear indicator (15). Remove: The bolts (16) The brake caliper Disengage the top part of the caliper between the pivot and the pivot support, in order to prevent the braking circuit from opening.	Remove: The suspension sphere (17), Using tool [3] The (18) bolt Uncouple the high pressure piping (19) from the suspension cylinder.
	Move aside the protector (20) (at "a"). Remove: The nut (21) The bracket (22) The bolts (23) The front suspension leg

Refitting

N.B.: Always fit new Nylstop nuts.
Refit:

• The front suspension leg
• The bolts (23), Tighten to 2.6 ± 0.3 daN.m
• The bracket (22)
• The nut (21)

Position: The protector (20).

N.B.: Refit a new seal (23). Couple the high pressure piping (19). Refit: The (18) bolt, Tighten to 2 ± 0.2 daN.m The suspension sphere (17), Tightening to 2.7 ± 0.2 daN.m Refit: The front brake caliper The bolts (16), tighten to 3 ± 0.2 daN.m Reconnect: The wires of the brake pad wear indicator (15). Insert the drive shaft into the hub. Put the brake hose supports (14) in place. Refit: The ABS sensor (13) The (12) bolt, tighten to 0.8 ± 0.1 daN.m The (11) bolt The nut (10) The (9) bolt The (8) bolt Refit without tightening: The nut (5) and its pin The anti-roll bar link rod (6) The nut (4) The nut (3) Fit a new nut (7). Tighten the nut (7) to 4.8 ± 0.5 daN.m.

"X" = 58 ± 5 mm. Position the front suspension lower arm to the dimension "X". Tighten: The nut (5) to 7.5 ± 1.1 daN.m The nut (4) to 5 ± 0.5 daN.m The nut (3) to 20.5 ± 2 daN.m Refit: The drive shaft nut, tighten to 34.5 ± 0.5 daN.m The cover (2) The pin (1) The wheel Tighten the wheel bolts. Fill and bleed the suspension circuit.

Part 2 - Removing / Refitting Rubber Bushes for Front Suspension Upper Support

Procedure after Removing Strut:

Tools

[1] removing mandrels (-).0548.A4. [2] removal cap (-).0548.A3. [3] guide bolt (-).0548.A1 + washer M10 (-).0548.A2.	[4] Refitting ring (-).0548.B3. [5] refitting guide (-).0548.B4. [6] refitting cover (-).0548.B5. [7] guide bolt (-).0548.B1 + washer M10 (-).0548.B2.

Remove: The bolts (5) The front suspension cylinder (6) The bolts (7) The front pivot upper support (8)

Immobilise the front pivot support in a jaw vice. Fit the tools [1], [2], [3] on the front flexible mounting (9). Extract the flexible mounting (9) by screwing in the screw of the tool [3]. Tighten the screw [3] to extract the rubber bush (9).

Refitting

CAUTION: Respect the direction of fitting for the rubber bushes (9).	Fit : The new rubber bush (9) Tools [4], [5], [6] and [7] Tighten the bolt [7] until the rear flexible mounting (9) is put in place. CAUTION: The fitting of the flexible bush must be done with some force. If the rubber bush is loose, replace the front pivot upper support.

Refit:

• The front pivot upper support (8)
• The bolts (7) (Without tightening it)
• The front suspension cylinder (6)
• The bolts (5) (Without tightening it)
• The front suspension leg

Tighten in the correct range:
The bolts (7) to 4.5 ± 0.6 daN.m
The bolts (5) to 2.4 ± 0.3 daN.m

blimey, thanks a lot Marc

[GiveMeABreak]

Yep, time to get the skin grafts ready John!

[furriegurrie]

This looks very similar to the setup of the C6. Do you know if it is in fact the same?
